14/06/2016 Weather for the Week Ahead

Hello. At this time of year, summer fetes and sports days clutter

our home calendars. What we need is a spell of prolonged sunshine.

Think again. It stays unsettled this week. Yet again,

Tuesday brings another day of slow-moving showers,

some heavy and thundery.

A spell of more persistent rain pushing in to the north-east

of Scotland after a glorious Monday here.

Cooler as well in the far north-east, 12 or 13 degrees.

In between the showers, if you get sunshine

we should see highs of 20 degrees, 68 Fahrenheit,

in the south-east.

Moving out of Tuesday, you can see plenty of showers

but they will fade away for a time, with the exception of the far

north, more persistent rain lingers throughout the night.

Temperatures stay widely into double figures.

But on Wednesday,

still that area of low pressure influencing the weather story

and we have still got more of a northerly flow to the north.

Underneath the cloud and the rain,

it will start to feel fresher, driving in outbreaks of rain

across central and southern areas of Scotland and a cooler feel here.

Sunny spells and scattered showers elsewhere.

If you dodge the showers and you get the sunshine,

shouldn't feel too bad but even so, temperatures down a degree are so.

Highest values of 19 degrees, only 11 to 13 in the far north and east.

Still that area of low pressure with us, still that northerly flow.

You can see that by the isobars starting to descend further

south and so a fresher feel perhaps for all by Thursday,

particularly into the north.

It will be cooler but showers should be fairly isolated, more widespread

across England and Wales. 11 to 15 degrees to the north,

highs of 17 to 20 further south.

Into Friday, again

a northerly flow taking over across the country

so despite some sunshine and a drier feel to the south,

temperatures a notch or so down, 17 or 18 at the very best.

We will start to see an area of high pressure

building from the south-west, the Azores High, but watch it,

already into Saturday it is starting to change shape.

That is going to be important with our six-to-ten-day outlook.

It does look as though the start to the weekend likely

to be the best day of the week.

Quieting down, drying up with more sunshine coming through.

So despite 12 to 18 degrees again, with the sunshine

it will feel a bit better.

This is the story throughout this week,

an area of low pressure anchored across the UK. Why?

Why is it not going very far?

It is all due, yes, you guessed it, to the jet stream.

A very weak jet at the moment,

so much so it is diffusing almost into two.

It doesn't have the oomph to push that area of low pressure

out of the way.

Hence the reason that each day this week is fairly typical,

sunshine and sharp, slow-moving showers.

Eventually it will move away and allow that Azores High to

build from the south-west but not for very long.

Start of the weekend looks promising,

but then the high-pressure tilts

and that potentially could allow, again, to open

the door to further low pressures moving in from the Atlantic.

So it will be a brief respite into the start of the weekend

before we see more showers returning.

So the longer outlook remains somewhat like this.

It does look as though the weekend will be slightly more promising,

a sunnier weekend, and as a result, it will feel a little warmer.

But the showers never too far away.

It does look as though further areas of low pressure into the early

half of next week are set to return.

More details coming up.
